Adding object into array and changing property of other objects in that array

Question

How can I at the same time add this object into an array and change property popup to false to every other object (if there is any) in that same array?

 this.setState({
            map: {
                ...this.state.map,
                areas: this.state.map.areas.concat({
                    coords: [evt.nativeEvent.layerX, evt.nativeEvent.layerY, 15],
                    popup: true,
                })
            }
        });

You can't do this in the same time, but you could use Object.assign method and map in order to set the popup property to false and then just concat the new item.

areas: this.state.map.areas.map(item => Object.assign(item, {popup: false})).concat({
   coords: [evt.nativeEvent.layerX, evt.nativeEvent.layerY, 15],
   popup: true,
})
